[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.

[0045] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0046] In the description of the present application, it should be noted that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present application and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present application. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0047] In the description of the present application, it should be noted that the use of terms such as "first" and "second" to limit components is merely to facilitate the distinction between corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present application.

[0048] The technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0049] Figure 1A schematic diagram of the structure of an X-ray source provided in one embodiment of the present application is shown in FIG. Figure 2 for Figure 1 An exploded diagram of the structure of the X-ray source is shown.

[0050] First, please refer to Figure 1 and Figure 2 , the X-ray source comprises: a metal shell 10, an X-ray tube (not shown), a high voltage generator (not shown), a first plug 20, an oil pump 30, a cooling device 40 and a second plug 50; the X-ray tube and the high voltage generator are both enclosed in the metal shell 10; the first plug 20 is fixed on the metal shell 10 and electrically connected to the X-ray tube through the high voltage generator; the oil pump 30 is fixed on the metal shell 10 and communicates with the metal shell 10; the cooling device 40 is communicated with the metal shell 10, and the cooling device 40 is used to accelerate the heat exchange between the X-ray tube, the high voltage generator and the external environment; the second plug 50 is fixed on the cooling device 40 and electrically connected to the oil pump 30. It should be noted here that the aforementioned X-ray tube specifically refers to a device for generating X-rays, which includes a cathode and an anode, and electrons are accelerated from the cathode and collide with the anode by applying a high voltage to generate X-rays. In order to generate a sufficiently high voltage to accelerate electrons, the X-ray tube needs to be connected to the high voltage generator. The high voltage generator can generate and adjust the required high voltage and transmit it between the anode and cathode of the X-ray tube. In this way, a sufficiently large electric field can be formed inside the X-ray tube to accelerate electrons and generate X-rays.

[0051] The X-ray source involved in the present application realizes detachable connection between each connection cable exposed outside the metal housing 10 and the internal electrical components by configuring the first plug 20 and the second plug 50. In the scenario where the X-ray source needs to be transported, since each connection cable of the X-ray source is not electrically connected to the internal electrical components, the connection cables will not be damaged or broken due to entanglement and pulling.

[0052] In some embodiments, the X-ray source includes insulating oil, which is contained in the metal housing 10 and soaks the X-ray tube and the high voltage generator. As an example, the insulating oil is insulating mineral oil with a cooling effect.

[0053] The metal shell 10 defines a cavity therein. The metal shell 10 is provided with a liquid inlet 10a and a liquid outlet 10b connected to the cavity. The liquid inlet 10a is used to communicate with a fin radiator 41 or a main body of a cooling device 40 to be described below, and the liquid outlet 10b is used to communicate with an oil pump 30.

[0054] like Figures 1 to 6As shown, in some embodiments, the metal shell 10 is roughly in a regular rectangular shape, and includes two first side walls 101 with relatively large areas and two second side walls 102 with relatively small areas. The two first side walls 101 and the two second side walls 102 are connected end to end in sequence to form a middle frame portion with openings at both ends. The metal shell 10 also includes a top wall 103 and a bottom wall 104. The top wall 103 is connected to one end of the middle frame portion and closes the side opening, and the bottom wall 104 is connected to the other end of the middle frame portion and closes the side opening. The top wall 103, the bottom wall 104 and the middle frame portion are collectively arranged to form the aforementioned cavity.

[0055] One of the two first side walls 101 is provided with a ray window that matches the shape of the ray probe of the X-ray tube. When the X-ray tube is assembled in the metal housing 10, the ray probe of the X-ray tube can be embedded in the ray window. Preferably, the ray window is located in the middle of the metal housing 10, so that the X-rays emitted by the X-ray tube have a more uniform coverage.

[0056] Continue as Figure 2 As shown, in some embodiments, the liquid inlet 10a and the liquid outlet 10b are both located on the top wall 103 , and the two are spaced apart along the length extension direction of the top wall 103 .

[0057] In some embodiments, in order to improve the safety performance of the X-ray source, the inner wall surface of the metal shell 10 is coated with a shielding layer, and the presence of the shielding layer can effectively absorb or reflect X-rays, thereby reducing the impact of radiation leakage. As materials for making such a shielding layer, metals or compounds with radiation absorption properties such as lead, tungsten, and bismuth can be listed.

[0058] In some embodiments, to reduce the weight of the X-ray source, the metal housing 10 may be made of die-cast aluminum or aluminum extrusion. It is understandable that the material selection of the metal housing 10 is actually diverse and is not specifically limited here. For example, in other embodiments, the metal housing 10 may be made of steel.

[0059] For the first plug 20, the embodiments of the present application do not limit its type, as long as it can meet the electrical performance requirements of the design. For example, in some embodiments, the first plug 20 is as follows: Figures 1 to 6 For another example, in some other embodiments, the first plug 20 is a power plug.

[0060] Continue as Figures 1 to 6 As shown, in some embodiments, the first plug 20 and the oil pump 30 are both located on one of the two second side walls 102 , and the first plug 20 and the oil pump 30 are disposed adjacent to each other.

[0061] For the cooling device 40, Figures 1 to 3As shown, in some embodiments, it includes a fin radiator 41 and a cooling fan 42 electrically connected to the second plug 50. The fin radiator 41 includes a fin radiator body and a plurality of cooling fins formed on the surface of the fin radiator body facing the cooling fan 42. Among them, the fin radiator body is fixed to the top wall 103, and the fin radiator body also defines an oil cavity. The side of the fin radiator body close to the top wall 103 can be connected to the liquid inlet 10a through but not limited to an oil pipe. The fin radiator body can also be connected through but not limited to a connecting pipeline of the oil pump 30. The cooling fan 42 is fixed to the side of the fin radiator body where the cooling fins are formed, and the cooling fan 42 is used to dissipate heat for the fin radiator body. For ease of understanding, the circulation path of the insulating oil is described below. Specifically, the heat generated by the X-ray tube and the high-voltage generating device in the working state is absorbed by the insulating oil stored in the cavity, and the temperature of the insulating oil is increased. The insulating oil with higher temperature can be transported to the plate-type radiator 41 under the pumping action of the oil pump 30. The plate-type radiator 41 completes the heat exchange of the insulating oil inside it under the accelerated airflow of the cooling fan 42. The insulating oil after heat dissipation is re-input into the cavity from the liquid outlet 10a for circulation. In this circulation path, the liquid outlet 10a can be used as the cold oil output port of the radiator body, and 10b can be used as the hot oil input port of the radiator body.

[0062] Furthermore, at least one heat dissipation fin is in a curved wave shape, thereby increasing the effective heat dissipation area, so as to improve the heat dissipation efficiency of the heat dissipation fan 42 for the insulating oil with a relatively high temperature flowing therethrough.

[0063] In some embodiments, the fin heat sink 41 may be an aluminum fin heat sink 41 .

[0064] like Figures 4 to 6 As shown, alternatively, the cooling device 40' includes a main body (not shown), a partition (not shown), a plurality of first cooling fins (not shown) and a plurality of second cooling fins (not shown). The main body is fixed to the top wall, and the partition is arranged in the main body to separate the first flow path space and the second flow path space arranged in an up-and-down manner.

[0065] The top of the main body is provided with an inlet and an outlet connected to the first flow path space, wherein the inlet and the outlet are both used for connecting an external refrigerant circulation device.

[0066] A plurality of first cooling fins are arranged in the first flow path space, and the plurality of first cooling fins are spaced apart from each other to communicate with the inlet and the outlet.

[0067] A plurality of second cooling fins are arranged in the second flow path space, and the plurality of second cooling fins are spaced apart from each other to communicate with the liquid inlet 10a.

[0068] For the second plug 50, the embodiments of the present application do not limit its type, as long as it can meet the electrical performance requirements of the design. For example, in some embodiments, the second plug 50 is as follows: Figures 1 to 6 For another example, in some other embodiments, the second plug 50 is a power plug.

[0069] like Figure 1 or Figure 2 As shown, in some embodiments, the second plug 50 is fixed on the same side of the fin radiator 41 as the oil pump 30. That is, the oil pump 30 and the first plug 20 are located on the same side wall of the metal housing 10, and the cooling device 40 is located on the other side wall of the metal housing 10 adjacent to the oil pump 30 and the first plug 20.

[0070] Alternatively, if Figure 3 or Figure 6 As shown, in some embodiments, the oil pump 30, the first plug 20, the second plug 50 and the cooling device 40 are all located on the same side of the metal housing 10. The advantage of this arrangement is that the components outside the metal housing 10 are arranged more compactly to save space occupied by the X-ray source.

[0071] It is understandable that the embodiments of the present application do not limit the fixing method of the first plug 20 and / or the second plug 50, as long as the sealing between the plug and the housing can be maintained and the insulating oil is difficult to leak from the gap between the plug and the housing. For example, in some embodiments, the first plug 20 and / or the second plug 50 are fixed to the housing through a sealing gasket. For another example, in other embodiments, a sealant is additionally applied to the gap between the plug and the housing.

[0072] like Figures 1 to 6 As shown, in some embodiments, the X-ray source includes a handle 60, which is fixed on the metal shell 10, and the handle 60 and the cooling device 40 are both located on the same side of the metal shell 10. Specifically, the handle 60 is in an inverted U shape, and both ends of the handle 60 are respectively fixed to the top wall 103 to confine the cooling device 40 therein. The handle 60 is provided to facilitate carrying and transporting the X-ray source.

[0073] Preferably, there are two handles 60, and the two handles 60 are spaced apart from the two opposite ends of the cooling device 40. Figures 1 to 6 As shown, the two handles 60 are spaced apart from opposite ends of the cooling device 40 along the length extension direction thereof.

[0074] like Figure 7As shown, in some embodiments, the X-ray source includes an X-ray source controller 70, which is contained in the cavity and immersed in insulating oil. The X-ray source controller 70 includes a high-voltage drive module 71, a filament control module 72, and a signal feedback module 73, which are electrically connected to the high-voltage generating device. The high-voltage drive module 71 and the filament control module 72 can respectively provide the high-voltage drive and filament current drive required for the operation of the X-ray tube, and the signal feedback module 73 can receive the high-voltage and anode current signals fed back by the X-ray tube to monitor the stability of the high voltage and anode current.

[0075] Continue as Figure 7 As shown, in some embodiments, the X-ray source includes a collimator 80, which is aligned with the ray window of the X-ray tube to align the X-ray beam emitted by the X-ray tube into a fan shape.

[0076] Based on the same technical concept, one embodiment of the present application further provides a detection device, which includes the X-ray source in any of the above embodiments. For the structure and function of the X-ray source, please refer to the above embodiments, and will not be described one by one here.

[0077] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
